Harris County sheriff's deputies arrested a man who they say punched his disabled girlfriend, stole her purse and unplugged her wheelchair, leaving her stranded, Harris County prosecutors said.

David Proulx, 49, of Humble, faces a felony charge of injury to a disabled individual, court records show. He was being held Thursday in the Harris County Jail in lieu of a $10,000 bond.

The victim, who suffered a brain injury nine years ago in a motor vehicle accident, told deputies the two were arguing at her Humble home Tuesday when things suddenly turned violent, according to an arrest warrant filed in the case.

Investigators said the suspect punched the woman in her face. "The (victim) has limited mobility and was unable to protect herself or avoid the defendant's strikes," the arrest warrant states.

After grabbing his girlfriend's purse from the arm of her wheelchair, Proulx disabled the wheelchair by pulling an electrical connection apart, leaving her stranded in the bathroom, prosecutors said.

The victim was discovered about an hour later by the suspect's sister, the complaint states. She called the victim's parents, who arrived to repair the wheelchair, and they called the sheriff's office.

Investigators said the woman had a swollen lip and mark under her eye "consistent with being struck."
